v0.5.0

This release is a major rewrite and cleanup. Quite a few things moved
around. Please take a look at the new code structure yourself.

The main `AcmeService` and `AcmeClient` API didn't change much.

This release includes an upgrade to Amp v2, which should give more
stability, especially for the DNS resolver and HTTP client.

v0.4.1

 - Fixed `OpenSSLCSRGenerator` to return a `Promise` instead of a
`Generator` and to resolve the promise with the CSR contents instead of
a boolean.

v0.4.0

 - Removed unnecessary parameters for CSRs (#15).
 - Moved challenge verifiers into their own classes.
 - Upgraded to `namshi/jose:^7`.
 - Moved generation of CSRs outside of `AcmeService` (#17).
 - Added `generateDns01Payload()`.
 - Retry when hitting the rate limit (#23).
